OKD-053 Tetrahedrite, Sphalerite, Galena, Quartz Casapalca, Peru. Ex. Dr. Steve Chamberlain Collection. Here is a large plate of outstanding crystals of exceptional size for the location. The piece measures 12 x 11 cm and is up to 5 cm thick. The sides are mineralized on much of the piece and there is no damage. The sphalerites are largest reaching over 4 cm each. They are nicely translucent, yellowish and complex in form. The tetrahedrites are exceptional in luster and reach 2 cm each. Their form is clean and attractive. The galena are also very complex and not as lustrous as the other minerals. All crystals are evenly dispersed on the matrix. A real winner. 580$

Two big cubes with slight octahedral modifications and a single cube which is highly modified by octahedral form. Green tint to these crystals which reach over 8 cm each.

OKB-577 Stilbite, Stevensite Pseudo after Pectolite Parrsboro, Nova Scotia, Canada. Ex. Dr. Steve Chamberlain collection, acquired from Dr. David Potter. What a wonderful piece. An exceptional 12 cm specimen with not one, but two pseudos ot 4 cm each. The best one of these I have ever seen had only a single ball, was smaller and as expensive as this one. This is a rare and exceptionally clean piece. 850$

OKB-573 Fluo- magnesio- kataphorate Tory Hill, Ontario, Canada. Known to the locals simply as hornblende, this is a exception example of the species. This was the best find I recovered from a 12 foot long pocket back in the 1990s which as, until now, resided in my personal collection. This fully terminated specimen has an aesthetic display and is wonderfully elongated. It has was recovered from the pocket in two pieces and has been repaired. The break is in the center of the main crystal and is noticeable when looked for. I have yet to see a hornblende crystal anywhere this impressive for sale. An important Canadian piece. Currently mounted on a custom glass stand with hot glue. 2,800$

OKB-574 Fluo- magnesio- kataphorate Tory Hill, Ontario, Canada. Ex. Dr. Steve Chamberlain Collection. Purchased from Ward's Science of Rochester, NY. Known to the locals simply as hornblende, this is a exception example of the species. 25 pounds of high luster, double and single terminated hornblendes to 22 cm each on feldspar. Approx. 30 cm specimen. Very good to rather crude terminations on these huge crystals. Here is the type of specimen which deserves its own case. Impressive piece. 1,700$

OKD-466 Rose Quartz on Milky Quartz Minas Gerias, Brazil. Second generation rose quartz crystals are set high on the matrix of crystallized milky quartz in a thick band visible from all sides of this fine specimen. A very large specimen from this famous producer of rare rose quartz crystals which measures 9.3 x 7 x 6 cm overall with individual crystals to 1.6 cm. There is some very minor damage which does not distract from the display characteristic which make this a highly aesthetic and very desirable specimen (but it has been taken into account when it comes to the specimen’s price). Sits nicely for display, super luster and wonderful form. This specimen has great views from all directions except one side. 1,400$

OKD-657 Herkimer Diamond Scepter Treasure Mountain Mine, Little Falls, New York. A beautiful pair of scepters which have been reattached. One crystal has a small chip to its stem and back edge, otherwise a damage free floater. Excellent deep black stems. Internal skeletal form. This fine grouping measures almost 8 cm wide with the largest crystal being 5.5 cm wide. Highly uncommon, aesthetic piece. I've never seen one quite like this beauty. 950$
